Democratic Party-aligned “dark money” powerhouse Patriot Majority USA collected half of the $30 million it raised last year from five anonymous donors, according to a Center for Public Integrity analysis of a new tax filing from the group.

Patriot Majority USA was a major player in the Democrats’ failed bid to retain control of the U.S. Senate last year — a time when many Democratic candidates decried the influx of “dark money” in politics.
